The agency added that the "majority of people who get the measles were unvaccinated".

Among the symptoms of measles are coughing, rash, high fever and red, watery eyes. All in all, for every 1,000 children who are exposed to the virus, one or two will die from measles.

If you develop symptoms of measles, the New Jersey Department of Health recommends that you call a health care provider before going to a medical office or emergency room.

Measles can also cause serious complications, such as pneumonia and swelling of the brain.

Measles can be spread through the air when someone coughs or sneezes. "Getting vaccinated not only protects you, it protects others around you who are too young to get the vaccine or can't receive it for medical reasons". As of the moment, local health agencies are reaching out to IL residents identified to have been potentially exposed to the measles virus at the airport.
